Acupuncture works by stimulating peripheral sensory nerves and their endings causing an increase in cutaneous blood flow and microcirculation, as well as release of neurotransmitters, neuropeptides, and hormones. SP6 Patch is a nanoscale nontransdermal device that mildly stimulates Stomach 36 (zusanli) and other acupuncture points. As stimulation of these points has been indicated to have an effect on hypothalamic function, it is of great research interest to investigate the effect of SP6 Patch on the physiology of organs that are affected by hypothalamic regulation. Bioelectrical tissue impedance data indicative of cellular physiologic organ function, using an Electro Interstitial Scan (EIS) system, were acquired from hypothalamus, pancreas, liver, intestines, kidneys, thyroid and adrenal glands in 10 (1 male, 9 females) volunteers while wearing the SP6 Patch daily for 1 week. EIS testing was performed at baseline with no patch, 30 min after wearing the patch, and after wearing the patch 12 h/day for 1 week. Subjects were instructed to keep well hydrated during the study period. All subjects served as their own control. The hypothesis was: The SP6 Patch worn 12 h/day on the Stomach 36 acupuncture point for 1 week, may significantly improve cellular physiologic functional status of different organs measured by EIS. All tested organs achieved significant improvement in their functional physiologic status after wearing the SP6 Pach 12 h/day for 1 week compared to baseline with an overall average statistical power > 89%. Based upon these results the hypothesis was accepted as true.

연구배경 : 생체의 운동은 움직임 자체를 수행하기 위한 근육, 관절 및 이를 관장하는 신경계와 운동중 적절한 산소를 공급하기 위한 심혈관계 및 호흡계의 조절이 동반되는 매우 복잡한 기전에 의하여 유지되고 있다. 이들의 상호관련성을 밝히기 위하여 많은 연구들이 진행중이나 특히 관절과 호흡중추의 연계성에 대하여는 아직도 연구가 미진한 편이다. 이에 본 연구는 관절의 정상적인 움직임이 호흡계에 어떠한 영향을 미치는지를 규명하고자 $\alpha$-chloralose로 마취한 고양이의 분당 호흡수, 횡격신경과 흡식신경섬유의 변화를 관찰하였다. 방법 : 26마리의 성숙한 숫고양이에서 슬관절 자극중 횡격신경 및 흡식중추신경의 활동성을 기록하기 위하여 쌍극백금전극과 탄소섬유전극을 이용하여 세포외에서 기록하였다. 슬관절을 자극하기 위하여 슬관절의 굴곡-신전운동, 슬관절 동맥을 통한 화학적인 자극 및 슬관절 신경의 전기적인 자극법 등을 사용하였다. 결과 : 슬관절의 정상 운동각도내에서 120 Hz.의 빠른 운동을 1분간 시킨 경우에는 분당호흡수와 분당호흡신경활동이 유의하게 증가하였으며 3분간 운동을 시킨 경우에는 호흡수, 일회호흡신경활동 및 분당호흡신경활동이 모두 유의하게 증가하였다. 그러나 60Hz.의 운동에 대하여는 전체적인 호흡활동에 뚜렸한 변화가 없었다. 과격한 운동중에 형성되는 젖산의 혈중농도와 같은 농도의 젖산을 슬관절내에 주입한 결과 주입후 30초 동안에 호흡수 이외의 일회호흡신경활동과 분당 호흡신경 활동이 유의한 증가를 보였다. 또한 potassium chloride에 대하여는 젖산의 경우와 유사한 반응을 보였으나 반응기간이 짧았다. 구심성 신경중 I, II군만을 선택적으로 흥분시킬 수 있는 강도인 1V로 슬관적 신경을 자극한 경우 자극기간에 한하여 호흡수를 제외한 일회호흡신경활동 및 분당호흡신경활동이 유의한 증가를 보였다. 또한 구심성 신경을 모두 흥분시키는 강도인 20V 자극에 대하여는 호흡계의 전체적인 항진효과가 있었으며 1V 자극에 비하여 매우 큰 반응을 나타내었다. 흡식중추의 신경세포에서 기록한 결과 횡격신경에서 나타난 반응과 유사한 결과를 얻었다. 결론 : 슬관절 구심성 신경중 제 I, II 군 신경의 흥분에 의하여 호흡중추는 직접적으로 활성화될 수 있으며 이러한 효과는 운동중의 슬관절로부터 중추로 유입되는 정보의 양에 비례하여 증가하는 것으로 생각된다. 따라서 이러한 사실은 슬관절의 정상적인 움직임에 의해서도 생체의 호흡기능이 항진될 수 있다는 것을 시사하고 있다.

Background: Lumbar zygapophysial joints are a common source of chronic lower back pain and radiofrequency thermocoagulation (RF) of the medial branches (MB) has been shown to be effective at providing substantial pain relief for chronic low back pain. Therefore, we carried out this study to determine the short term outcomes and prognostic factors of RF on the MB of patients with lumbar facet syndrome. Methods: We performed RF in fourteen patients who showed greater than 80% pain relief up to three times after a diagnostic MB block was conducted using 0.3 ml of 0.5% bupivacaine. Using 10 cm curved electrodes with 10-mm active tip, a 60 second, $80^{\circ}C$ lesion was made after electrical stimulation at 50 Hz for sensory and 2 Hz for motor nerve testing. The degree of pain relief was then assessed after 2 weeks, and again after 3 months using a visual analog scale (VAS) and a four point Likert scale. The outcome was regarded as 'success' if at least a 50% reduction in the VAS was observed. Possible prognostic factors between the two groups were also evaluated Results: The success rate was 71.4% (10/14) after three months of follow-up. However, there were transient complications, such as neuritis like syndrome, in 4 patients. In addition, short symptom duration and low minimal voltage (< 0.4 V) for sensory stimulation were shown to be the relevant prognostic factors for a successful outcome. Conclusions: RF may be an alternative to repeated MB block or intraarticular injection for palliation of lumbar facet syndrome. For better outcomes, early diagnosis and strict patient selection should be coupled with efforts to avoid anatomically incorrect RF.

The purpose of this study was to provide experimental evidence and theoretical background for the applicability of bilateral transfer paradigm to the rehabilitation programs for children with hemiplegic cerebral palsy. Children with hemiplegia, which means unilateral motor disabilities, display abnormal motor and postural patterns of the affected side due to hemiparesis, spasticity, and sensory disorders, resulting in a decreased motor abilities of the affected side compared to unaffected side. Accordingly, they tend to rely on the unaffected limb for everyday activities, which further deteriorates the functions of the affected side by causing associated reaction, abnormal postural patterns, and hypertonus. Rehabilitation programs developed for children with hemiplegic cerebral palsy include neurodevelopmental treatment, application of cast or splint to unaffected limb, neuromuscular electrical stimulation, and task oriented model. These programs, however, have several drawbacks, such as discontinuity in treatment effect and psychological hatred to the force use of the affected side. In order to solve these problems and enhance the efficiency of the rehabilitation programs, it is required to maximize the use of the affected side without hatred. Characteristics of the control system, such as temporal coupling and spatial assimilation between limbs and neural crosstalk at different levels of central motor pathway, suggest that the bilateral transfer paradigm may enhance the efficiency of the rehabilitation programs for children with hemiplegic cerebral palsy.

Purpose: To investigate the effect of an augmented reality (AR) system on muscle strength and function level of the paretic lower limb and the balance ability in the early rehabilitation program of acute stroke patients. Methods: The participants (30 or fewer days after stroke) were randomly assigned to receive intervention with an early rehabilitation program using an AR system (n=1) or an early rehabilitation program consisting of functional electrical stimulation and tilt table use (n=1). Patients in both subjects received interventions 4-5 times a week for 3 weeks. Results: In the paretic limb muscle strength, AR subject was increased from 15 to 39.6 Nm and Control subject was increased from 5 to 30.2 Nm. The paretic limb function of AR subject motor function was increased from 8 to 28 score and Control subject motor function was increased from 6 to 14 score. But sensory function was very little difference between the two subjects (AR subject: from 4 to 10 score, Control subject: from 3 to 10 score). In the balance ability, AR subject had more difference after intervention than control subject (AR subject: 33 score, Control subject: 22 score). Conclusion: The early rehabilitation program using the AR system showed a slightly higher improvement in the motor function of the paretic lower limb and balance ability measurement than the general early rehabilitation program. The AR system, which can provide more active, task-oriented, and motivational environment, may provide a meaningful environment for the initial rehabilitation process after stroke.

Dysfunction of the inferior alveolar nerve may result from trauma, diseases or iatrogenic injury. The development and refinement of an objective method to evaluate this clinical problem is highly desirable and needed, especially concerning for an increasing medico-legal issue. Evoked potential techniques have attracted considerable attention as a means of assessing the function and integrity of nerve pathways. The purpose of this study was to characterize the Sensory Evoked Potentials(SEPs) and Somatosensory Evoked Potentials(SSEPs) elicited by electrical stimulation of mental nerve. SEPs and SSEPs were measured and analyzed statistically before and after needle injury on the inferior alveolar nerve of Sprague-Dawalye rats. Measuring SEPs was more sensitive in evaluation of the recovery of sensory function from inferior alveolar nerve injury then measuring SSEPs but we measured SSEPs in the hope of providing a safe, simple and objective test to check oral and facial sensibility, which is acceptable to the patient. We stimulated mental nerve after needle injury on the inferior alveolar nerve and SEPS on the level of mandibular foramen and SSEPs on the level of cerebral cortex were recorded. Threshold, amplitude, and latency of both of SEPs and SSEPs were analyzed. The results were as follows ; 1. Threshold of SEPs and SSEPs were $184{\pm}14{\mu}A$ and $164{\pm}14{\mu}A$ respectively. 2 SEPs were composed of 2 waves, i.e., N1 N2 in which N1 was conducted by II fibers and N2 was conducted by III fibers. 3. SSEPS were composed of 5 waves, of which N1 and N2 shower statistically significant changes(p<0.01, unpaired t-test). 4. SEPs and SSEPs were observed to be abolished immediately after local anesthesia and recovered 30 minutes later. 5. SEPs were abolished immediately after injury. N1 of SSEPs was abolished immediately and amplitued of N2 was decreased($20.7{\pm}12.2%$) immediately after 23G needle injury, but N3, N4 and N5 did not change significantly. Recovery of waveform delayed 30 minutes in SEPs and 45 minutes in SSEPs. 6. The degree of decrease in amplitude of SEPs and SSEPs, after 30G needle injury was smaller than those with 23G. SEPs recorded on the level of mandibular foramen were though to be reliable and useful in the assessment of the function of the inferior alveolar nerve after injury. Amplitude of SSEPs reflected the function and integrity of nerve and measuring them provided a safe, simple and abjective test to check oral and facial sensibility. These results suggest that measuring SEPs and SSEPs are meaningful methods for objective assessment in the diagnosis of nerve injury. N1 and N2 of SSEPs can be useful parameters for the evaluation of the nerve function following a needle injury.

Anatomy: Facet joint syndrome most often affects the lower back and neck and refers to pain that occurs in the facet joints, which are the connections between the vertebrae in the spine that enable the spine to bend and twist. Many physicians have believed that the usual lesion of facet syndrome was an anatomical impairments of facet joint itself.. Facet joint injection using local anesthetics is a reliable method for the diagnosis and treatment for facet syndrome. Etiology: One of many possible causes is imbalances that can occur in stress levels, hormone levels, and nutritional levels. These imbalances can adversely affect posture, which can lead to neck and back pain. The common disorder called facet syndrome exhibits lower back pain, with or without, radiating pain to buttock and thigh due to facet joint arthropathy. Pain in the facet joint is supposedly the secondary effect of narrowing of joint space by sustained muscle contracture around joints. Syndrome: Facet joint syndrome tends to produce pain or tenderness in the lower back that increases with twisting or arching the body, as well as pain that moves to the buttocks or the back of the thighs. Other symptoms include stiffness or difficulty standing up straight or getting out of a chair. Pain can be felt in other areas such as the shoulders or mid-back area. Treatment: Non-drug treatments include hot packs, ultrasound, electrical stimulation, and therapeutic exercises. Stimulating blood flow using massage or a hot tub may also help. Alternative treatments include yoga and relaxation therapy. If your pain persists after trying these treatments, a surgical procedure called radiofrequency rhizotomy, which destroys the sensory nerves of the joint, may bring relief. Facet joint injection has been helpful in diagnosis and therapy for this facet syndrome. Radiofrequency thermocoagulation of medial branches is known to be an effective method of relieving pain caused by facet joint problems. We conclude that spasmolytic treatment of muscles connecting the two vertebral articular space would be better for treatment and diagnosis of facet syndrome rather than facet block with local anesthetic and steroid only.
